MARINE CURRENT TURBINES REVEALS DETAILS OF SEAGEN’S GENERATING PERFORMANCE
Tuesday, November 3rd 2009
Lisbon, Portugal: Speaking today at the Lisbon International Ocean Power Conference, Peter Fraenkel, Technical Director and co-founder of Marine Current Turbines, the Bristol company that designed and developed SeaGen, the world’s only commercial scale tidal stream turbine, told delegates that SeaGen is running at full power and fully automatically, exactly as planned.
Peter Fraenkel said: “We are delighted with SeaGen’s performance. It is running reliably and delivering more energy than originally expected in an extremely aggressive environment. It should be remembered it is being driven by a wall of water 27m deep, similar to the height of the
SeaGen has already delivered over 350MWh of power into the Northern Irish electricity grid. The twin generators typically produce an average of 5MWh of electricity during the 6¼ hours of each ebb and each flood tide. This is enough energy to meet the average electricity needs for 1500
The SeaGen turbine, with its twin 16m diameter rotors, is officially accredited by OFGEM as a “
Martin Wright, Managing Director of Marine Current Turbines, commented: “We are delighted to have moved on from the initial period of commissioning and testing to demonstrating that this is a practical method of generation that really does do exactly what it says on the label. It is a hugely significant milestone for the company to be selling electricity consistently and earning revenue.”
Although SeaGen has been operational for most of this year, it was not until September that consent was given to operate it without having to have environmental scientists (marine mammal observers) on board and onshore. This was an initial requirement under the licensing arrangements to ensure that SeaGen did not adversely affect the marine mammals that are a protected feature of the local waters and restricted SeaGen’s uninterrupted running. However extensive experience gained so far suggests the seals and porpoises are not at any significant risk and as a result SeaGen is now permitted to operate unattended and by remote control, as was originally intended.
For the time being. an operator onshore will continue to monitor a sonar image of the passing flow which can show up any seal that ventures too close to the rotors, and the operator has the facility to stop the machine. As confidence and the body of evidence grows, it is expected that full running will be permitted in the near future.
Martin Wright added: “Building on our experience in Strangford Lough, the team at MCT are working to deploy tidal turbine arrays in UK and overseas waters, and we are working on new scaled-up developments from SeaGen that promise to generate power at a lower cost. The expectation is that this radical new technology can be developed within five to ten years to make a significant contribution to our future energy needs. Given suitable market incentives, SeaGen demonstrates that marine renewable energy is at the cusp of forming the basis for a new
